So I am looking for some assistance with cooking, but not really food, at least not for human consumption!! I am doing some research for a friend of mine. I have a pet guinea pig and I have a food mixture for him, but the issue is that the foo store only provides it in the form of a grinned up powder. I want to take this oats/soy/bean mix and turn it into a bar for him to gnaw on. Can someone assist me on how to do this. To get an idea of the texture I am working with, it is like sugar or cream of wheat, only oats, beans, soy, sugar, etc. Thank you in advance for any help.
